This is not true. Original rating was just empty 1-star (common competitor tactic) because MiHaniKo copied/published a competing extension (he did this to other DeepSeek extensions too). Then I reported him, so he added a reason to look less fake (more details here: https://github.com/semanticdata/firefox-chatgpt-in-sidebar/issues/4)

Mozilla reviewer refused to delete this fake review (didn't even have words at time of report) for some bizarre reason so that is why I leave my warning here (extension 100% works, I make 10000+ commits on GitHub yearly @ https://github.com/adamlui, all my extensions are obviously well-maintained)
